Title: [Increased enzymatic activity of antioxidant protection of the heart in the adaptation of rats to short-term stress exposure].

The most labile enzyme was catalase (35% increase). During stress in nonadapted animals the enzyme activity decreased, as compared to the control, while in the group of adapted animals with subsequent stress the activity was even higher than in the control. During initiation of lipid peroxidation in the heart homogenates in vitro there was a 3-fold increase and a 1%-fold decrease in the oxidation intensity in rats exposed to stress and in adapted animals, respectively. The role of adaptation activation of cardiac antioxidant system in the prevention of stress-induced heart damage is discussed.Read More
